SEMrush & Ahrefs run from $29 to $999 a month. OpenSEO does the same job under an MIT license, with no subscription at any tier.
I built 17+ SEO & AEO tools in one app: keyword research, backlink analysis, rank tracking, site audits, AI visibility tracking and local rank grids, all built on one crawler instead of six disconnected products.
💯 Free means free, not a trial.
Site audits run 117 technical checks across up to 500 pages. Your Google Search Console data, keyword research and a local rank grid for any business cost nothing. Fresh SERP, backlink and keyword lookups are pay-per-call, so rank tracking starts at $0.02 a check. You pay for the data you actually pull, never for a seat. But you get $5 bonus credit to get started.
🤖 Built for AI agents: 76 MCP tools expose the whole platform to Claude, ChatGPT or any MCP client, and the AI visibility tracker shows where your site surfaces across 120+ models.
Self-host it with one Docker command, or use the hosted version. No feature gates, no license keys, no seat counts. Every line is public: github.com/duckduckdeploy/openseo
